Submit #865260: Pimzino spec-workflow-mcp 2.2.6 Path Traversalinfo

TitlePimzino spec-workflow-mcp 2.2.6 Path Traversal
DescriptionThe GitHub project Pimzino/spec-workflow-mcp contains a path traversal or arbitrary file access vulnerability. Attacker-controlled path input is used for local file-system access without restricting the resolved path to an approved directory, allowing read or write access outside the intended workspace depending on the affected endpoint or tool. A local proof of concept confirmed the file access impact and the vendor was contacted through https://github.com/Pimzino/spec-workflow-mcp/issues/220. Public reproduction record: https://github.com/gongyanyugyy/public_exp/issues/3.
